I found that reference interesting not so much for its listing of any new names, but for how it showed that, despite the sound of them, names like 'Souvenir de la Princesse de Lamballe' may be quite modern inventions. He says (The GST Rose Book, p. 99) "The name 'd'Orsay' came from Nancy Lindsay, but may well not be the original," and who knows how many more there are?

For the benefit of those who do not have GST's Rose Book handy, I'll try to summarize the gist of page 27 without trampling copyright underfoot. GST found that what he grew as Empress Josephine looked very similar to Redoute's painting of R. turbinata/Rosier de Francfort, which differed only by having bristly hips. "[R. x francofurtana's] garden forms include the variety 'Agatha' , which appears to be identical with my 'Pope Piux IX'... The botanical portraits of R. francofurtana in old books (apart from Redoute) record a much less impressive and double rose, such as [lengthy reference omitted] which depicts a very prickly type." On page 6 of the same book, he mentions "the so-called 'Empress Josephine', which proved to be a form of R. francofurtana."

I think all he meant by that, is that he successfully identified it as one of a class that used to contain white, pink, red and purple flowers, some single, others double or very double, short upright plants, arching bushes, and climbers that might be trained for 12-20 feet, but which is now limited to survivors one could count on one hand. The species rose and Agatha are both triploid, but Empress Josephine is tetraploid, and visibly differs from R. x francofurtana.

I hope that helped, rather than make things more confusing.
